After a first 4 week tour in May I parked my new Burstner on the drive, emptied fresh and grey water tanks leaving taps open, gave a general clean and placed the dehumidifier inside to dry out any remaining condensation. Over the last 6 weeks I have been emptying as much as a litre of water every 3 days and it hasn't stopped yet!! No sign of damp anywhere. It's a mystery!! Any ideas anyone ??
